Abstract

PURPOSE: The Danish Prostate Symptom Score (DAN-PSS) is known to be a good tool for evaluating the voiding symptoms and sexual life stati in the treatment of BPH. Recently, linguistic translations into Korean have been performed with validity and reliability tests. The DAN-PSS is composed of 24 questionnaires on voiding symptom and 6 on sexual function stati.
MATERIALS AND METHODS
An urologist and special translators participated in the translation of the DAN-PSS into Korean. The validity and reliability of the questions on the sexual stati of the Korean DAN-PSS were tested. A total of sixty-nine men, aged from 41 to 69, who visited out institute for voiding problems, and diagnosed with BPH, were included for the questionnaires. They all replied to the Korean DAN-PSS questionnaires within 48 hours after completing the DAN-PSS questionnaires. A further forty-seven men replied twice to the Korean DAN-PSS, at 2 weeks interval. Both the validity and the reliability of the Korean DAN-PSS were evaluated.
RESULTS
There was no statistically significant difference between the DAN-PSS and its Korean version (p>0.05). Similarly, there was no statistically significant difference in the 2 sets of answers for the Korean version of the DAN-PSS at 2 week interval (p>0.05).
CONCLUSIONS
The translation of the DAN-PSS into Korean was valid and reliable. The Korean DAN-PSS is as a good a tool as the DAN-PSS in the evaluatione of sexual life stati.
